Polyurethane (PUR, TPU, CPU and PU) is a polymer composed of a chain of organic units joined by carbamate(urethane) links. While most polyurethanes are thermosetting polymers that do not melt when heated,thermoplastic polyurethanes are also available.
Polyurethane polymers are traditionally and most commonly formed by reacting a di- or polyisocyanatewith a polyol. Both the isocyanates and polyols used to make polyurethanes contain on average two or more functional groups per molecule.
Some noteworthy recent efforts have been dedicated to minimizing the use of isocyanates to synthesize polyurethanes, because the isocyanates raise severe toxicity issues.
Nonisocyanate based polyurethanes (NIPUs) have recently been developed as a new class of polyurethane polymers to mitigate health and environmental concerns.
Polyurethane products often are simply called “urethanes”, but should not be confused with ethyl carbamate, which is also called urethane. Polyurethanes neither contain nor are produced from ethyl carbamate.
Polyurethanes are used in the manufacture of nonflexible, highresilience foam seating
rigid foam insulation panels microcellular foam seals and gaskets
durable elastomeric wheels and tires (such as roller coaster, escalator and skateboard wheels)
automotive suspension bushings electrical potting compounds
high performance adhesives
surface coatings and surface sealants
synthetic fibers carpet underlay
difficult-plastic parts condoms and hoses.
Polyurethanes are engineered elastomers that can be cast into sheets or rods as well as finished parts. Polyurethanes are graded depending on their hardness or durometer. They are available in a wide variety of durometers ranging from Shore 50A (extremely soft and rubbery) to Shore 75D (hard and stiff).
Polyurethanes are extremely tough, resilient, and abrasion resistant. They are used for a wide variety of applications including bumpers, wheel covers,roller covers, snow plow edges, and screen printing squeegees.
